It was not, on the whole, a good month for lame-duck Los Angeles City Councilman Richard Alatorre. There was, for instance, the April 13 election to pick his successor. About which two things were, from the incumbent’s point of view, noteworthy. The first was that the candidate he endorsed, neophyte Luis Cetina, got about 8 percent of the vote, finishing fifth. Cetina pulled this off, in one of L.A.’s most heavily blue-collar neighborhoods, after Alatorre helped wangle him the heaviest union endorsement in the race — that of the entire Service Employees regional council.Worse still, the top vote scorer was a kid named Nick Pacheco, who, far from being Alatorre’s protégé, was that of Alatorre’s primal earthly enemy, Eastside political shaker Henry Lozano.These were fiery signs in the heavens. From the top to the bottom of the ticket, the 14th District’s voters renounced and repudiated Alatorre’s entire 28-year career in the Assembly and City Council.
